MITSUBISHI ELECTRIC Changes for the Better

A holistic approach to predictive maintenance


Predictive maintenance

Manufacturers need to increase machine availability and reduce unscheduled downtime in order to respond to global competition, requiring techniques that will help to manage maintenance and maximise reliable production. Condition monitoring offers a predictive approach to plant maintenance, ensuring optimum asset performance while keeping downtime to a minimum.

The Smart Condition Monitoring (SCM) solution from Mitsubishi Electric provides an integrated approach to monitoring the condition of individual assets and enables a holistic approach to be taken to monitoring the asset health of the whole plant. Individual sensors provide both an in-built ‘traffic light’ warning indication at the machine, but at the same time plain text information from multiple sensors is transferred over Ethernet to the smart sensor controller for in-depth monitoring and more detailed analysis.

Benefits & functions

Operational benefits

Linking multiple sensors into the sensor control system enables the controller to analyse patterns of operation that are outside the norm, with a series of defined alarm conditions that provide alerts that attention is needed.

The SCM analysis provides detailed diagnostics, offers suggestions for where additional measurements should be taken, and provides maintenance staff more precise error identification with identifying the root case and even recommendations as to what rectification actions should be taken, with clear text messages presented to personnel. This information can be networked to higher-level systems for ongoing trend analysis across all of the assets around the plant.

  • Predictable maintenance month before breakdown
  • Reliable online monitoring of the machine
  • Intelligent process monitoring
  • Easy installation
  • Intuitive operation
  • Long term storage of historical data
  • Flexible, expandable system
  • Full service around machine diagnosis


The Smart Condition Monitoring system supports a number of functions that aid in predictive maintenance:

  • Bearing defect detection
  • Imbalance detection
  • Misalignment
  • Lack of lubricant detection
  • Temperature measurement
  • Cavitation detection
  • Phase failure recognition
  • Resonance frequency detection


The Smart Condition Monitoring system overcomes the limitations of traditional sensors. Although these indicate a developing problem on an individual machine, they give no detail about what the problem could be or how serious it might be. The SCM system provides an improved solution for:

  • Electric motors
  • Geared motors
  • Vacuum and fluid pumps
  • Ventilators and fans
  • Gearboxes
  • Compressors
  • Spindles and machine tools
  • Separators and decanters

With its ready-made Smart Condition Monitoring Kits Mitsubishi Electric offers powerful complete solutions for easy integration into existing applications. Compared to conventional monitoring concepts, the modular Plug & Play system does not only analyse classic machine data such as temperature, but also vibration-dependent parameters.

Mitsubishi Electric offers three different kits:

SCM Kit DRIVES for the lower power range with the integration of up to 2 sensors
SCM Kit COMPACT for up to 6 sensors
SCM Kit MODULAR for up to 14 sensors and more

Smart Condition Monitoring Kit-DRIVES

The SCM Kit-DRIVES offers a ready-made integrated condition monitoring solution for permanent installation and integration into existing applications. This is possible thanks to the combination of three powerful individual components; frequency inverter, operator display and a ready-made vibration sensor. The frequency inverter included in the package is your wild-card for all drive tasks. The system can be extended to up to two sensors. Implementation is easy by using plug & play via the display, even without expert knowledge in the field of condition monitoring.

1 SLD = Super light duty (110 % for 60 s, 120 % for 3 s); LD = Light duty (120 % for 60 s, 150 % for 3 s); ND = Normal duty (150 % for 60 s, 200 % for 3 s); HD = Heavy duty (200 % for 60 s, 250 % for 3 s)

2 Type FR-AF842 frequency inverters must be operated with an FR-CC2 current converter, which must be ordered separately. For additional details, please see the frequency inverter catalogue.

The Smart Condition Monitoring Kit-1 COMPACT

Simple decision. The SCM Kit-1 COMPACT is one of our SCM solutions and offers outstanding value and reduces costly downtime. It is a completely preconfigured condition monitoring solution for new or existing applications with one vibration sensor and is optionally expandable with up to six sensors.

The Smart Condition Monitoring Kit-1 MODULAR XL

A simple decision. The SCM Kit-1 MODULAR XL is one of our SCM solutions with outstanding value and reduces costly downtime. It is a completely preconfigured condition monitoring solution for new or existing applications with a single vibration sensor, and is optionally expandable with up to fourteen sensors. This solution offers plain text alarm messages with maintenance suggestions, timestamp and status / diagnostics display for predictive maintenance. A remote visualization via VNC server support in the local network, or externally via routers, is possible, as well Industry 4.0 support with bidirectional continuous data handling. The package is your upgrade joker for predictable maintenance.

Please note, for applications with more than fourteen sensors, such as production lines and bigger systems, Mitsubishi Electric offers project based SCM solutions. In such cases, please contact your Mitsubishi Electric sales person.
